Characteristic Structures on Film Induced by Femtosecond Laser Pulse Irradiation
Abstract:
With femtosecond laser pulse (130 fs, 800 nm, 1 kHz pulse repetition frequency) irradiation on Au/Cr film stack, several nanostructures were obtained. The influence of laser parameters such as fluence(0.5J/cm2,2J/cm2) and the number of pulse were investigate. With single pulse irradiation, the nanoline and periodic ripple structures were obtained for the pulse fluence of 0.5J/cm2 and 2J/cm2, respectively. The formation mechanism of those nanostructures were discussed.
